Another thing that doesn't make sense from a business perspective, is scouting out young talent to fill these roles of Cyke/Jean/Storm, only to dispatch them in favor of the OT cast in X-4/5. That would seem like a waste. Of course most of the FC cast was dumped after DoFP, but they held on to the the actors they had to have, notably JLaw and Hoult. I don't want to see Jean/Cyke/Storm relegated to FC teeny bopper treatment. Jean would have to be the lead female in a FC 3 movie. You want an actress with talent. You could carry those actors into an AoA movie and film a lot of backstory, flashbacks, and what not, but I don't think they'd be able to play their older versions. Could you go from FC3 in 2017 to an AoA in 2020 or 2021, and forward the timeline 20-30 years with the same actors? Not sure that would be practical, even with makeup and CGI.
